IMPROVEMENT IN MILK-SAFES.

Specification forming part of Letters Patent No. 123,453, dated February6, 1872.

To all whom it may concern:

Be it known that I, JAMES W. CASE, of Ypsilanti, in the county of`Washtenaw and State of Michigan, have invented certain new and usefulImprovements in Milk-Safes; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawing and to the letters of reference marked thereonwhich form a part of this specification.

In the milk-safes now most generally in use there is a central uprightshaft, upon which or around which a series of shelves revolve, saidshaft passing' through the centers of the shelves, but by such anarrangement a great portion of the surface ofthe shelves-n amely, thecenteris rendered useless, and only such articles can be placed on themas do not take up any more room than from the central sha-ft to theouter edge of the shelf. rIo remedy this defect is the object of myinvention; and it consists in a series of shelves, arranged one abovethe other within a safe, each shelf having its own support, andrevolving independently of the others. My invention also consists in themeans for supporting, guiding', and revolving each separate shelf, aswill be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l represents a vertical section. Fig. 2 is a plan View; and Fig.3 is a bottom view of one ofthe shelves.

A represents a milk-safe, constructed in the usual manner, either roundor polygonal, of panels and wire-cloth, and with doors of suitable size.In this safe is a series of shelves, B B, with a horizontal cross-bar,C, underneath each shelf, each end of said cross-bars being firmlyfastened or secured to the sides of the safe. Upon the cross-bar C theshelf revolves by means of a wood or iron pivot, c,

through the center of the shelf, and a connecting circle, D, or flangedwheel made of wood, iron, or other suitable metal, screwed to thecross-bar,x To this circle or ilanged wheel the shelf' is connected bymeans of two parallel grooved slats or cleats, E E, screwed or otherwisesecured to the underside of the shelf, thereby strengthening andsteadying the motion of the shelf', and holding it firmly in position.This support and connection removes all obstructions to the free use ofthe whole surface of the shelves, so that the safe can be used forprotecting cheese and other large articles.

In place of the cross-bars C C for supporting' the shelves, I maysubstitute an arm, C', as shown, under the bottom shelf in the safe, ora bracket, made of wood or iron, and eX- tending from either side of thebody of the safe to the center, and at this end of said arm or bracketis a pivot on which the shelf B revolves. In this case I also employ africtionroller, G, located above the outer end of the arm or bracket,and bearing upon the upper surface at the edge of the shelf, so as toproperly steady the same and keep it in its position.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is n l. A series of revolvingshelves, arranged one above the other within a safe, each shelf havingan independent support on the crossbars C C, thus exposing the entireupper surface, substantially as set forth.

2. The combination of the shelf B, cross-bar C, pivot ci, wheel D, andguides E E, all constructed and arranged substantially as and for thepurposes herein set forth.

In testimony that I claim the foregoingl as my own I affix my signaturein presence of two Witnesses:
